BBRC, I would suggest that the Ackley books may contain some improved handload data for the improved cartridges. The only quirk may be that the powders used then may be slightly different than what is available today. It will be an experiment and will require that you carefully observe signs of pressure and determine where you are at. I would think you will definitely want to use your chronograph as well.
Also, what was a 222 1/2 cartridge? I assume it was an improved .222 Rem, but in what way?
Thanks, Peter.
